Looking at Google Maps it appears several other buildings in the area also straddle the border. The reporter mentioned an insurance dispute in passing, but it would be interesting to have more details on how it all works from a legal perspective. Presumably they get two different property tax bills. Are two different building codes enforced depending on which part of the building you're in?
I’d imagine many of the same considerations come into play when a structure straddles a state line in the US. I wonder how that’s handled?
There was a building in the outer Washington, DC, suburbs that straddled a county line. Somehow or another its status became subject to a vote twenty-five or thirty years ago--though the electorate eligible to vote on this must have been tiny.
And I did once meet a programmer who lived or had live in a house straddling the New York/New Jersey line NW of New York City. I didn't ask about the tax status.
